In particular, since the worker has to fix the fence using wires or bolts one by one, the working time is delayed, and the work efficiency is lowered due to cumbersome and inconvenient work.

In addition, when a part of a fence or a mesh network fixed to each other is damaged, easy replacement and reuse are practically impossible, so there is a limitation in use that can only be used as a one-time use.

As a prior art for solving this problem, Korean Patent Registration No. 10-1117083 (published on February 22, 2012) is disclosed. As shown in Figure 1, in order to assemble the prefabricated fence, first, using the anchor bolt 115, the reinforcement H-beam 112 is inserted on the anchor plate 114 to fix the reinforced post 111, When the post 111 is fixed, the clip body 131 is assembled to the post 111, and the assembling of the clip body 131 includes a locking protrusion 131a provided on one side of the clip body 131 and a locking groove provided on the post 111 ( 111a).

This fence puts the clip cap 132 on the clip body 131 so as to cover the mesh network, and the clip cap 132 and the clip body 131 are integrally formed using the clip fastener 133 to the post 111 . to be fixed on In the fixing, the clip fastener 133 penetrates the cap fastening hole 132a of the clip cap 132 and the protrusion fastening hole 131e of the clip body 131 to the mesh fastening hole 111b formed in the post 111. made by concluding

However, the prefabricated fence according to the prior art has a problem in that the work of fixing the mesh network to the post is delayed by fixing the mesh network to the post with a clip body and a clip cap and then fastening it with a clip fastener. However, there was a problem in that the assembly work was cumbersome, such as having to fix the mesh after accurately setting the position of the mesh.

Therefore, as well as stably supporting all four edges of the mesh network, a means for quickly, easily, and firmly assembling the mesh network and each post was required.
